Olson, Gary,`lnd., assignor' to Nationaly Tube Companypa corporationnof New Jersey Application` February'z'z, '1932.-v sefiai No. 595,593 :s claims. (ci. ,s3-125) This invention'relates to measuring apparatus and, while notH limited thereto, relates more particularly toY measuring lapparatus formeasuring the length` of long objects; such.. as pipe sections,

vi bars?, mds and I'Olled metal shapes. .1'

One objectk of the present invention is to provide a'measuring apparatus of .this class which is operable by one man and forma single station.` y y class ywhich is adaptable for installation on a weighing scale platform or other 'worktable so as to permit an .object to be measured at the same time it is being weighed or worked upon.

Referring more vparticularly `to the drawings,

the numeral 2 designates a scale platform which deck or .top vface of the platform 2 is provided with a slot 4 which extends for an appreciable distance lengthwise of the platform. One end of the platform 2 is extended as at 5 to form a suitable supporting. structure for the 'operating mechanism' of the measuring apparatus. The rear platform beam 6 is extended at both ends of the platform and has shafts -7 and 8 mounted adjacent its opposite ends. Sprockets 9 and 10 are mounted on the shafts '7 and 8, respectively, and a sprocket chain 12 is trained over the `sprockets 9 and 10, and an L-shaped stop member 14 has its horizontal leg connected to the opposite ends of the chain 12 forming a continuous carrying member.v The vertical leg ofthe upwardly through the slot 4 and engage the end of the object being measured.

The shaft 8V carrying the sprocketv 10 is coupled 'to av speedvreducing'mechanism 17 which, in'70 'turnisc ou'pled to a motor 18 so as'tlov provide a power drive for reciprocating the chain 412 'and stop member 14.

After the length of thefobject has been determined by the operator he will reverse the motor 18 so as to `shift-the stop member 14v and chain 12 to the left, thereby providing'sufflcient clearance for the movement of the next object to be measured. f M Y' While I have` shown and described one specific embodiment of my invention, it will be understood that I do ynot wish to be limited thereto since various modifications may be made Without 11 2.
